Abstract It has been increasingly popular to acquire short tau inversion recovery (STIR) images in brachial plexus magnetic resonance imaging after injection of a gadolinium-based contrast medium in order to improve blood vessel suppression. This example highlights the potential pitfall that the signal of plexus lesions and anatomical structures such as the dorsal root ganglia can be suppressed in gadolinium-enhanced STIR compared with nonenhanced STIR images.
